“…Therefore, smooth surfaces have greater heat transport, causing a colder feeling when touching them [38]. This is in line with other studies, where rough materials are rated as more warm, soft and pleasant [39]. Wood is perceived as a rough material and therefore this perception might influence other psychological attributes such as warm, soft and pleasant attributes.…”

Abstract:Wood is generally associated with being practical, aesthetic and economy-friendly. Using wood in interior settings also can be based on psychological expectations and assumptions, as wood is attributed as warmer, more homely, more relaxing and more inviting. However, when investigating psychological differences, wood is usually compared to carpets, glass, leather, stone, or plastic but is not compared to a visually similar material such as laminate. The aim of this study is to analyze and compare the various psychological characteristics related to wooden and laminate materials in interior settings. The experimental design was a 2 × 2 design (material, sequence) with repeated measures for material. Forty participants were asked to evaluate a framed piece of wood floor and a framed piece of laminate floor regarding technical, practical, and psychological aspects. Further, three questions about one's purchase decision were asked. The results show that the wooden floor was evaluated significantly better than the laminate floor regarding "materials and processing", "atmosphere", and "values and symbolic functions". For the criterion "health", a tendency in favor of wood could be found. In addition, the participants would more likely recommend and purchase wooden products and also accept more deficiencies in wooden products.

“…Adjective texture dimensions other than roughness, hardness, and stickiness have been examined by other researchers, and these dimensions include soft/harsh, thin/thick, and relief and hardness (Picard et al 2003) or blur and clarity (Gescheider et al 2005). The relationship between the texture perceptual space, on the one hand, and roughness, hardness, and stickiness, on the other, is different in direct touch and indirect touch.…”

“…Although other putative adjectives have been used to describe textures including "thin", "thick", "relief", "harsh" (Picard et al 2003), "blurred", and "clear" (Gescheider et al 2005), exactly how these descriptors relate to the primary dimensions is not clear. In the present study, we concentrate on the three primary dimensions of "hardness", "stickiness", and "roughness".…”

Considerable information about the texture of objects can be perceived remotely through a probe. It is not clear, however, how texture perception with a probe compares with texture perception with the bare finger. Here we investigate the perception of a variety of textured surfaces encountered daily (e.g., corduroy, paper, and rubber) using the two scanning modes-direct touch through the finger and indirect touch through a probe held in the hand-in two tasks. In the first task, subjects rated the overall pair-wise dissimilarity of the textures. In the second task, subjects rated each texture along three continua, namely, perceived roughness, hardness, and stickiness of the surfaces, shown previously as the primary dimensions of texture perception in direct touch. From the dissimilarity judgment experiment, we found that the texture percept is similar though not identical in the two scanning modes. From the adjective rating experiments, we found that while roughness ratings are similar, hardness and stickiness ratings tend to differ between scanning conditions. These differences between the two modes of scanning are apparent in perceptual space for tactile textures based on multidimensional scaling (MDS) analysis. Finally, we demonstrate that three physical quantities, vibratory power, compliance, and friction carry roughness, hardness, and stickiness information, predicting perceived dissimilarity of texture pairs with indirect touch. Given that different types of texture information are processed by separate groups of neurons across direct and indirect touch, we propose that the neural mechanisms underlying texture perception differ between scanning modes.

“…The many studies in the psychophysics of texture and roughness perception unfortunately contribute little insight to the haptics engineer because these studies rarely speak of the same quantities, although there is a general agreement that roughness has perceptual significance [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], even if it is nearly impossible to define it unambiguously from the physical characteristics of the touched object [15].…”

The Spatial Spectrum of Tangential Skin Displacement Can Encode Tactual Texture

Abstract-The tactual scanning of five naturalistic textures was recorded with an apparatus capable of measuring the tangential interaction force with a high degree of temporal and spatial resolution. The resulting signal showed that the transformation from the geometry of a surface to the force of traction, and hence to the skin deformation experienced by a finger is a highly nonlinear process. Participants were asked to identify simulated textures reproduced by stimulating their fingers with rapid, imposed lateral skin displacements as a function of net position. They performed the identification task with a high degree of success, yet not perfectly. The fact that the experimental conditions eliminated many aspects of the interaction, including low-frequency finger deformation, distributed information, as well as normal skin movements, shows that the nervous system is able to rely on only two cues: amplitude and spectral information. The examination of the "spatial spectrograms" of the imposed lateral skin displacement revealed that texture could be represented spatially despite being sensed through time and that these spectrograms were distinctively organized into what could be called "spatial formants". This finding led us to speculate that the mechanical properties of the finger enables spatial information to be used for perceptual purposes in humans without any distributed sensing, a principle that could be applied to robots.
